Printed circuit board (PCB) automatic detection production line and application method thereof

Abstract

The invention relates to a printed circuit board (PCB) production line, in particular to the PCB automatic detection production line and an application method thereof. The PCB automatic detection production line comprises a board dividing module, a detection module, a conveying module, a first mechanical arm, a code scanner, a second mechanical arm and an NG board storage area, wherein the conveying module is connected with the board dividing module; the first mechanical arm, the code scanner and the detection module are arranged on the conveying module; and the second mechanical arm is arranged on the conveying module and the NG board storage area. The PCB automatic detection production line provided by the invention overcomes the defects of a traditional production line, automatic detection is achieved, double stations are designed for board dividing and detection, and the detection efficiency is improved. Most importantly, the layout of the production line is adjusted, and the accuracy of board detection is improved. Meanwhile, NG boards are automatically and sequentially arranged through the mechanical arms, so that workers can conveniently record and overhaul the NG boards, and the board utilization rate is increased.

Description

technical field [0001] The invention relates to a PCB board production line, in particular to a PCB board automatic detection production line and a use method thereof. Background technique [0002] At present, there are mainly three methods for PCB board sub-board inspection, one is completely manual operation; the other is an improvement on the first method, semi-manual operation; the last is to use a milling cutter for board sub-boarding. The first method is used more, and this traditional inspection production line is completed by 7 people. Manually complete the electrical inspection of the PCB board and then divide the boards, manually record the good and bad boards and place them separately. The production line requires a lot of human resources, the output is 600 pieces / hour, and the testing efficiency is low. Moreover, workers will gradually become fatigued during continuous work, which affects the accuracy of detection. [0003] The second method is that the worker...

Problems solved by technology

Although this method has high detection efficiency, the vibration caused by the milling cutter will still cause damage to the PCB when the milling cutter is used to divide the board.

Moreover, the milling cutter needs to be replaced frequently, which is costly and affects the efficiency of the enterprise.

[0005] The most important thing is that the above three methods all have a fatal shortcoming, that is, the process of detecting first and then dividing the board will not be able to detect the damage caused by the dividing board to the sheet, so the detection accuracy is slightly poor

It may cause some damaged PCB boards to flow into the market during the board splitting process, which will affect the company's reputation

[0006] In order to solve the problems of low detection efficiency, high cost, and poor accuracy of traditional production lines, the invention discloses a PCB board automatic detection production line and its use method
